Contractor situation - how to resolve??

We contracted through My Flooring America, a brick and mortar business, to remove old carpet and tile floors and install new glue down wood floors. About 1700 square feet downstairs and 1250 square feet upstairs. Included foyers, hallways, two living areas, two dining areas, the kitchen and two bedrooms.

Everything was going fine. The floors looked great and we were pleased. The end of the project though is a disaster. They installed 1/2" x 7/8" shoe molding the wrong way. The X/Y axis is wrong. In other words, they installed the 7/8" side down on the floor instead of up on the side of the existing base moldings. I got a knock on my door. They were through and asked me to come out and inspect.

I went a bit ballistic and ask why they installed it that way. The installer said his site inspector had come by and told them to so they could cover the gaps between the wood and the existing moldings.

That tells me they installed the flooring incorrectly and did not cut the boards to fit close enough to the walls and were trying to cover up their mistakes.

Since then, I've discovered the following items:

1. the transitions between the new wood floors are plastic, not wood, and they are cut short and don't fit edge-to-edge in between the door jambs.
2. they did not remove the tile under the dishwasher and it is visible.
3. they did not cope out any corners, using butt ends.
4. I found moldings that were not even nailed in place.
5. they have splices where they tried to piece together moldings in the middle of a run where a single piece would have fit, AND they used butt ends instead of mitered splices.
6. they damaged a piece of home theater electronics and didn't tell me.

At this point in time, we still owe about $5000 and have not paid it. We've paid for everything up to this point. I've personally been in to their office. I have written them a very detailed description of the problems and after ten business days have gone by, they have not responded.

I contacted their HQ in the Houston area yesterday and was told I would be contacted by someone. Of course, nobody has contacted me.

What are my options? The flooring was installed the week before Christmas. They have a 60 day guarantee that if we aren't happy they will take it up and replace it. We like the floor. It looks great, but the molding and other issues just kills the whole installation. I know I can pull in a good flooring and trim carpenter to do this, but I am not willing to touch it until I speak to someone from the company, and so far, nobody has reached out to me.
